iPhone SE sale date in India

As said, the iPhone SE (2020) will go on sale in India starting May 20 at 12pm (noon) on Flipkart. As at the moment, the delivery and sale of non-essential goods via e-commerce platform are only permitted in areas that are marked as Orange and Green by the government, owing to the coronavirus pandemic, therefore the consumers living in the Red zones will not be able to order the phone unless government further relaxes the restrictions before May 20. A new set of guidelines from the government are expected in the coming days. There is no clarity on the availability of iPhone SE (2020) via brick and mortar stores. Hence you may not be able to get hold of phone any soon if you are not in relaxed zones.
